My passion for my extension/research appointment emanates from my strong desire to support New York agriculture. To support that passion, I conduct a vigorous applied research program that focuses exclusively on New York agriculture. Last year, we conducted over 50 experiments at the Aurora Research Farm and on 11 farms throughout New York State to determine the best corn silage hybrids, soybeans varieties, and management practices for corn, soybean, and wheat. I strongly believe in disseminating the results of my research program to New York growers so I extensively publish my results in extension publications and I drive through New York State during the winter presenting the research results. I also have a keen interest in the science behind my applied research so I work enough fundamental science into a few of my experiments each year so I can publish the results in journal articles. This keeps me current with the literature and keeps me active in our annual Society Meetings.

Research Focus

My research program focuses on the environmental, biotic, and management interactions that influence the growth, development, yield, and quality of corn and soybeans in New York. I frequently conduct farmer-participatory research in which farmers operate field-scale equipment while testing different crop management practices in 10-20 acre corn or soybean experiments on their farms. We have found that farmers value field-scale studies on commercial farms more than small-plot research on University farms. We have averaged about 50 experiments on 12 farms per year in New York over the last 5 year period. I also conduct the corn silage hybrid trials and soybean variety trials in New York State and disseminate this information in a timely manner so New York dairy producers and soybean producers can make informed decisions on hybrid or variety selection.

Outreach and Extension Focus

My extension program, supported strongly by my applied research program, recommends the best management practices for corn, soybeans, and wheat in New York. The targeted audience for my statewide educational program includes extension educators, agricultural practitioners ("multipliers "), crop and dairy producers, and government agency personnel. I disseminate my applied research information to the targeted audience via winter workshops, the Department extension newsletter, Department extension reports, and field days. I also chaired the Crop and Soil Management Statewide Program Committee (SPC) and Program Work Team (PWT) from 1992 through 2006 in which I worked closely with committee members (agricultural practitioners, farmers, extension agents, government agency personnel, and extension faculty) in developing statewide extension activities in field crop production. Some accomplishments of the committee include development of the New York and subsequently Northeast Certified Crop Adviser (CCA) program, development of the field crops section of the Agricultural Systems Initiative, and coordination with the New York Corn Growers Association in sponsoring the annual New York Field Corp and Feed Crop Industry Days, and the New York corn grain and silage yield contests. I was appointed Department Extension Leader in July of 2007, a position that I also held from 1988 through 1995. During my tenure as Department Extension Leader from 1988 through 1995, we launched the Department newsletter, What's Cropping Up, and resurrected the Aurora Field Day, which had not been held for the previous four years.
